Here is what I've done. This is not a tutorial. It is simply what I've done. I am not responsible if your 005 become pinball parts. hope this helps.
Remove caseback
remove crown guard
Unscrew crown screw a few turns till crown is loose and able to pull out. DO NOT UNSCREW FULLY!
Take the bitch out
Add rubber o-rings (i took these off of a spare crown I had laying around)
The o-rings stacked (depending on how much you dremel the crown is how many orings you need.
The crown dremeled
Insert crown and tighten screw.
The Finish product.
